[SCIENTIFIC DISCOVERY] Metal in water, penetrating inside your hair wash after wash, is one of the major causes of hair breakage. But did you know that porous hair has even higher risk of breaking as it absorbs up to 2x more water with metal? Through daily aggressions like chemical processing, heat styling or UV, micro-breaks multiply on the hair surface and cavities occur in the cortex, causing hair to get porous and absorb excess water with metal. Micro-breaks are a disruption of the protective cuticle layer which are the first signs of damage. This leads to higher risks of breakage. [INNOVATIVE TECHNOLOGY] Anti-porosity technology to treat hair when it is the most vulnerable to water: before the shampoo. It is concentrated with 2% Glicofiller, an active that has a dual effect both on surface and cortex, to prevent excess absorption of water with metal. On the surface: it coats the fibre and refills 1 million hair micro-breaks, in 1 use. Inside the fibre: it penetrates the hair and fills down to the cortex. This new pre-shampoo treatment is part of the Metal Detox range, a full anti-metal protocol to help prevent hair breakage and colour fade, providing up to 99% less breakage when the full range is used. [REFILL 1 MILLION HAIR MICRO-BREAKS, IN 1 USE] Deep penetration with long-lasting efficacy. Up to 96% less breakage in 1 use and anti-porosity. Hair is intensely moisturised: Up to 72h nourishment, smoothness and softness. Instantly plumped, hair is full-bodied and feels healthier. [INSTANT DETANGLING] Instant and efficient detangling on all hair types. Prepares hair for cleansing and eases shampoo usage. [PROFESSIONAL FORMULA] Lightweight, concentrated gel texture that instantly and deeply penetrates the fibre. Instant action, no pausing time needed. An addictive fragrance with a unique tech signature, thanks to a memorable citrus top associated with distinctive musky woods. For optimal results, use on wet hair before layering with Metal Detox shampoo, then rinse and follow with the mask and oil. When layering your shampoo directly on top, you're eliminating 1 rinsing step compared to a classic rinse-off pre-shampoo, limiting water consumption.
